The most important apparition of the 20th century approved by the Catholic Church is Fatima. It was reported that during Our Lady’s farewell to Sister Lucy at Fatima in 1917, the Blessed Virgin used these words, “Goodbye till San Sebastian of Spain.” Since that time, over 300 apparitions have been reported to the Vatican.
All light in the heavens will be extinguished, and there will be great darkness over the whole earth. Then the sign of the cross will be seen in the sky, and from the openings where the hands and the feet of the Savior were nailed will come forth great lights which will light up the earth for a period of time. This will take place shortly before the last day.
